Use tarantool version: Tarantool 1.6.8-586-g504e151 It installed from epel. I use tarantool on sphia mode:
log_space = box.schema.space.create('logs',
    {
        engine = 'sophia',
        if_not_exists = true
    }
)
log_space:create_index('primary', {
        parts = {1, 'STR'}
    }
)
I have 500.000 records and make select request:
box.space.logs:select({'log_data'})
it takes aboute 1min. Why so slow ?
unix/:/var/run/tarantool/g_sofia.control> box.stat()
